Blue-Tip Screw-Bolt 6.5 x 100 Zn

The Blue-Tip Screw-Bolt 6.5 x 100 Zn is a masonry screw-bolt that threads directly into a pre-drilled hole in concrete or block without needing a separate plug. It’s manufactured from zinc-plated steel, giving it a durable protective coating suited to general indoor and light outdoor use. Its hardened, blue-tipped thread cuts its own grip in the masonry for a fast, strong, removable fixing.
